Description

Technical Field

[0001] This utility model relates to the field of tobacco appliance technology, and in particular to a static pressure display device and a static pressure display system for tobacco appliances. Background Technology

[0002] Currently, range hoods can remove cooking fumes, odors, heat, and some moisture generated during cooking, thereby improving the kitchen environment and protecting family health. The air volume and air pressure of a range hood are important indicators for judging its suction power. Air volume refers to the volume of air that a range hood can remove per unit time, while air pressure refers to the range hood's ability to overcome the resistance of the flue and expel cooking fumes outdoors. Consumers should choose a range hood with appropriate air volume and air pressure according to their actual needs.

[0003] In related technologies, range hood manufacturers typically demonstrate the performance of range hoods by directly attaching objects to the air intake. However, this method fails to effectively showcase the range hood's performance, thus failing to attract consumers and impacting sales. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a static pressure display device for a range hood, which can better display the air volume and air pressure of the range hood.

[0005] This utility model further proposes a static pressure display system for a smoke machine.

[0006] The static pressure display device for a range hood according to this utility model includes: an adsorption component and a mounting component. The adsorption component has an adsorption chamber, the top of which is open to communicate with the air intake of the range hood. The mounting component is disposed at the bottom of the adsorption component for hanging a load-bearing component.

[0007] According to the static pressure display device for range hoods of this utility model, an adsorption component is set at the air intake of the range hood. The adsorption chamber in the adsorption component forms an open opening, which is connected to the air intake. A hanging component is set at the bottom of the adsorption component, and loads of different weights are hung on the hanging component. After the range hood is started, the air intake generates suction on the adsorption chamber, and the hanging component can hang a load of sufficient weight. In this way, consumers can intuitively feel the air volume and air pressure of the range hood, thereby meeting consumers' psychological expectations and making it easier for consumers to choose their favorite product.

[0008] In some examples of this utility model, the adsorption assembly includes: a base plate, the mounting member being connected to the bottom of the base plate; and a sealing member, the sealing member being disposed on the base plate, the sealing member forming the adsorption cavity on the base plate, and the sealing member sealingly engaging with the connection when the adsorption assembly is connected to the surface of the range hood where the air intake is located.

[0009] In some examples of this utility model, there are multiple seals, each extending along a corresponding side beam of the frame; or there is a single seal in a ring shape; or the seal is an elastic seal with an inner cavity.

[0010] In some examples of this utility model, the adsorption assembly further includes: a frame disposed on the top of the base plate, a seal disposed at the top edge of the frame, and the base plate, the frame, and the seal together defining the adsorption cavity with the opening.

[0011] In some examples of this utility model, the mounting component includes a base and a mounting part, wherein the base is connected to the bottom of the adsorption assembly, and the mounting part is connected to the bottom of the base.

[0012] In some examples of this utility model, the base is configured as a suction cup, which is adsorbed onto the bottom of the adsorption component; or the base is integrally formed with the bottom of the adsorption component; or the base is configured with a magnetic structure, and the bottom of the adsorption component is provided with a metal base plate, and the base is magnetically adsorbed onto the base plate through the magnetic structure.

[0013] In some examples of this utility model, the static pressure display device for the range hood further includes a connector for connecting the load-bearing component to the mounting component.

[0014] In some examples of this utility model, there is one mounting member, which is disposed at the bottom center of the adsorption assembly; or there are multiple mounting members, which are distributed at intervals on the bottom of the adsorption assembly and symmetrically arranged about the bottom central axis of the adsorption assembly.

[0015] The static pressure display system for a range hood according to this utility model includes: a range hood, a load-bearing component, and a static pressure display device for the range hood as described above. The range hood is provided with a suction panel having an air inlet. When the range hood is running and the opening of the adsorption chamber is connected to the air inlet, the range hood creates a negative pressure in the adsorption chamber through the air inlet, so that the static pressure display device is adsorbed onto the air inlet panel. The load-bearing component is connected to the mounting component and applies a force opposite to the suction force of the range hood to the static pressure display device through the mounting component, thereby displaying the static pressure of the range hood during operation while resisting the suction force of the range hood.

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-7 This invention describes a static pressure display device 100 for a range hood according to an embodiment of the present invention. The static pressure display device 100 is applied to a static pressure display system 1000 for a range hood to display the performance of the range hood.

[0022] like Figures 1-6 As shown, the static pressure display device 100 for a range hood according to this utility model includes: an adsorption component 10 and a mounting component 20. The adsorption component 10 has an adsorption chamber 11, and the top of the adsorption chamber 11 forms an opening, so that it can be connected to the air intake 210 of the range hood 200. The mounting component 20 is disposed at the bottom of the adsorption component 10, so that it can be used to hang heavy objects.

[0023] Understandably, the range hood 200 has an air intake 210 at its bottom. When the range hood 200 is powered on, the fan inside the range hood 200 starts working, and the air intake 210 can draw the surrounding air into the range hood 200. This allows the range hood 200 to remove the surrounding fumes, odors, heat, and some moisture, thereby improving the kitchen environment and protecting the health of consumers.

[0024] The adsorption component 10 and the mounting component 20 constitute the main structure of the static pressure display device 100 of the range hood. The adsorption component 10 has an adsorption chamber 11 with an open side. The open side is opposite to the air intake 210. When the adsorption component 10 is adsorbed onto the air intake panel 220 of the range hood 200, the adsorption chamber 11 is connected to the air intake 210, thus forming a closed space between the adsorption chamber 11 and the air intake 210. After the range hood 200 is powered on, the adsorption chamber 11 is drawn into a negative pressure chamber by the suction of the fan, which allows the adsorption component 10 to be better adsorbed onto the air intake panel 220 of the range hood 200.

[0025] Since the range hood 200 is located in the kitchen, the air intake 210 is mostly facing downwards or at an angle. The bottom of the adsorption component 10 is equipped with a hanging component 20, which can hang several loads. The weight of the loads and the suction force of the air intake 210 form an opposite force. When the weight of the loads reaches the critical point, the adsorption component 10 and the range hood 200 become loose until they are completely separated. Finally, the maximum load-bearing capacity is confirmed. This allows consumers to intuitively feel the suction power of the range hood 200, thus fully demonstrating the performance of the range hood, meeting consumers' psychological expectations, and making it easier for consumers to choose their favorite product.

[0026] For example, the load can be a weight, dumbbell, or other object with a significant mass. Using the formula P=F / S, F=mg=P*S, where P is pressure, F is the suction force generated by the air inlet 210 on the adsorption chamber 11, S is the area of ​​contact, m is the mass of the load, and g is the acceleration due to gravity, the magnitude of the suction force generated by the air inlet 210 on the adsorption chamber 11 can be accurately determined, thus allowing for the calculation of the airflow and air pressure of the range hood 200.

[0027] Therefore, by setting an adsorption component 10 at the air intake 210 of the range hood 200, the adsorption chamber 11 in the adsorption component 10 forms an open opening, which is connected to the air intake 210. A hanging component 20 is set on the bottom of the adsorption component 10, and different weights of loads are hung on the hanging component 20. After the range hood 200 is started, the air intake 210 generates suction on the adsorption chamber 11. The suction force and the weight of the loads form opposite forces. The hanging component 20 can hang loads of sufficient weight. This allows consumers to intuitively feel the air volume and air pressure of the range hood 200, thereby fully demonstrating the performance of the range hood 200, meeting consumers' psychological expectations, and making it easier for consumers to choose their favorite product.

[0028] Among them, such as Figures 2-6 As shown, the adsorption assembly 10 includes a base plate 12 and a sealing member 18. The mounting member 20 is connected to the bottom of the base plate 12, and the sealing member 18 is disposed on the base plate 12. For example, the sealing member 18 is disposed on the top edge of the base plate 12. The sealing member 18 forms an adsorption cavity 11 on the base plate 12. When the adsorption assembly 10 is connected to the surface of the range hood 200 where the air intake 210 is provided, the sealing member 18 is sealed and fitted with the connection.

[0029] In other words, a mounting bracket 20 is provided on the lower surface of the base plate 12, allowing the load-bearing component to be mounted on the bottom of the base plate 12 via the mounting bracket 20. This allows different weights to be applied to the base plate 12. The sealing component 18 is located on the base plate 12. When the adsorption assembly 10 is installed in the range hood 100, the sealing component 18 and the surface of the range hood 200 with the air intake 210 are pressed against each other. There is a certain height difference between the sealing component 18 and the base plate 12 in the vertical direction. This allows the sealing component 18 and the base plate 12 to define the adsorption chamber 11. The adsorption chamber 11 can correspond to the air intake 210, thereby allowing the range hood 200 to generate... The suction force acts within the adsorption chamber 11, and the sealing element 18 extends around the opening. This ensures the space of the adsorption chamber 11 and facilitates the connection between the sealing element 18 and the surface of the range hood 200 with the air intake 210. The sealing element 18 and the surface of the range hood 200 with the air intake 210 form a sealing fit, which seals the gap between the base plate 12 and the range hood 200. This ensures that all the suction force generated by the range hood 200 acts between the air intake 210 and the adsorption chamber 11, preventing the adsorption assembly 10 from falling off the air intake panel 220 and ensuring the sealing reliability of the adsorption chamber 11.

[0030] In addition, such as Figures 2-6 As shown, the adsorption assembly 10 also includes: a frame 13, which is disposed on the top of the base plate 12, and a seal 18 is disposed at the top edge of the frame 13. The frame 13, the base plate 12 and the seal 18 together define an adsorption chamber 11 with an opening.

[0031] In other words, the frame 13 is located at the top of the base plate 12, the hanger 20 is located at the bottom of the base plate 12, the frame 13 and the hanger 20 are located on the upper and lower sides of the base plate 12, and the frame 13 can extend along the edge of the base plate 12. The seal 18 is located at the top edge of the frame 13, and the seal 18, the frame 13 and the edge of the base plate 12 are connected sequentially from top to bottom. This allows the seal 18, the frame 13 and the base plate 12 to define the adsorption cavity 11, and the seal 18 and the frame 13 are located at the edge of the base plate 12, sealing... The component 18 does not occupy the space of the adsorption chamber 11, thus defining a larger space for the adsorption chamber 11, which is sufficient to demonstrate the suction power. An opening is formed at the top of the adsorption chamber 11. After the upper surface of the sealing component 18 comes into contact with the range hood 200, the air intake 210 connects with the opening. After the range hood 200 is started, the air intake 210 begins to work, and a suction force is generated between the air intake 210 and the adsorption chamber 11. The suction force and the weight of the load-bearing component generate a repulsive force, so that consumers can intuitively feel the air volume and air pressure of the range hood 200.

[0032] For example, the frame 13 can be an aluminum profile frame, and the width of the side beam of the aluminum profile frame can be 18mm, 20mm, 22mm and 25mm, etc. This can not only ensure the strength of the frame 13, but also ensure that the adsorption cavity 11 has enough space, thereby ensuring that the frame 13 is not easily broken by the suction force.

[0033] The base plate 12 can be either a metal plate or a glass plate. A metal plate ensures the strength of the base plate 12, while a glass plate allows consumers to visually observe the working status of the air intake 210. If the base plate 12 is a metal plate, the frame 13 can be welded to the metal plate. If the base plate 12 is a glass plate, the frame 13 can be connected to the glass plate with adhesive. Furthermore, the glass plate needs to be of high strength to ensure the strength of the base plate 12.

[0034] Alternatively, such as Figures 2-6 As shown, there are multiple seals 18, which extend along the edge of the base plate 12. Specifically, the corresponding side beams of the frame 13 correspond one-to-one with the edge of the base plate 12. This facilitates the placement of each seal 18 on the upper surface of the frame 13, ensuring the coverage area of ​​the seals 18 on the frame 13 and making it easy to replace the seals 18 if they fail. For example, there can be four seals 18, which can be respectively placed on the first side beam 16 and the second side beam 17 that are positioned opposite each other.

[0035] Alternatively, the seal 18 may be a single, ring-shaped element, facilitating its installation on the edge of the base plate 12. Specifically, the seal 18 may be installed on the upper surface of the frame 13, allowing for easy disassembly and installation, thus saving installation time. For example, the seal 18 may be integrally mounted on the opposing first side beam 16 and the opposing second side beam 17.

[0036] Among them, the sealing element 18 can be an elastic sealing element with an inner cavity. This not only ensures the sealing between the surrounding part of the air intake 210 of the range hood 200 and the adsorption component 10, but also provides a certain elasticity between the surrounding part of the air intake 210 of the range hood 200 and the adsorption component 10, thereby preventing the adsorption component 10 from colliding with the bottom of the range hood 200 and affecting the mutual repulsion between suction and gravity, thus ensuring the intuitive display of the suction power of the range hood 200.

[0037] In particular, such as Figure 3 and Figure 4As shown, the base plate 12 has a first side 14 and a second side 15 arranged opposite to each other, with the second side 15 connected between the first side 14; the frame 13 includes a first side beam 16 and a second side beam 17 arranged opposite to each other, with the first side beam 16 respectively arranged on the first side 14 and the second side beam 17 respectively arranged on the second side 15, with the second side beam 17 connected between the first side beam 16.

[0038] Understandably, the edge of the base plate 12 is divided into a first side 14 and a second side 15, and the frame 13 is composed of a first side beam 16 and a second side beam 17. The first side 14 extends along the front-back direction of the base plate 12, and the second side plate extends along the left-right direction of the base plate 12, or the first side 14 extends along the left-right direction of the base plate 12, and the second side plate extends along the front-back direction of the base plate 12. For example, if the base plate 12 is rectangular, the first side 14 and the second side 15 are the length and width of the rectangle, respectively. This makes it convenient for the bottom edge to be positioned opposite to the air intake 210 and to be completely covered below the air intake 210.

[0039] The first side beam 16 extends along the front-rear direction of the base plate 12, and the second side beam 17 extends along the left-right direction of the base plate 12. Alternatively, the first side beam 16 extends along the left-right direction of the base plate 12, and the second side beam 17 extends along the front-rear direction of the base plate 12. The first side beam 16 is located on the first side 14, and the second side beam 17 is located on the second side 15. This design defines the adsorption cavity 11 between the first side beam 16, the second side beam 17, and the base plate 12, and maximizes the adsorption cavity 11, thereby maximizing the suction power of the range hood 200. For example, the first side beam 16 and the second side beam 17 form a rectangular frame, and the base plate 12 is connected to the lower surfaces of the first side beam 16 and the second side beam 17. This allows the base plate 12 and the frame 13 to form a semi-enclosed space, namely the semi-enclosed adsorption cavity 11. When the frame 13 contacts the bottom of the air inlet 210 of the range hood 200, the air inlet 210 can provide suction to the adsorption cavity 11.

[0040] In addition, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the mounting component 20 includes a base 21 and a mounting part 22. The base 21 is connected to the bottom of the adsorption assembly 10, and the mounting part 22 is connected to the bottom of the base 21.

[0041] It is understandable that the base 21 and the mounting part 22 constitute the main structure of the mounting part 20. The base 21 is set on the lower surface of the base plate 12 and is located in the center of the base plate 12. This can balance the suction and gravity. The mounting part 22 is set at the lower end of the base 21. The mounting part 22 can place several loads. This allows the mounting part 22 to provide a place for the loads, thereby making it easier to increase the number and weight of the loads to observe the suction of the range hood 200.

[0042] Alternatively, the base 21 can be a suction cup, which adheres to the bottom of the adsorption assembly 10. This facilitates the installation and removal of the base 21 and the adsorption assembly 10, and also ensures the suction force between the base 21 and the base plate 12, thus facilitating the demonstration of the suction power of the range hood 200. For example, the bottom of the adsorption assembly 10 can form a smooth plane, which facilitates the adsorption of the suction cup to the bottom surface of the adsorption assembly 10, thereby ensuring the adsorption capacity between the suction cup and the adsorption assembly 10.

[0043] Alternatively, the base 21 and the bottom of the adsorption component 10 are integrally formed, which facilitates processing and manufacturing, facilitates the movement of the base 21 and the adsorption component 10, reduces the force error between the base 21 and the adsorption component 10, and thus ensures the mutual repulsion display effect of suction and gravity.

[0044] Alternatively, the base 21 may have a magnetic structure, and the bottom of the adsorption assembly 10 may have a metal base plate 12. The base 21 is magnetically attached to the bottom of the adsorption assembly 10 via the magnetic structure. The metal base plate 12 readily adheres to the magnetic structure, facilitating the installation and removal of the base 21 and the adsorption assembly 10. This also ensures the magnetic force between the base 21 and the base plate 12, thus demonstrating the suction power of the range hood 200. For example, the base 21 may be a magnet, as magnets readily adhere to metal, facilitating the connection between the base 21 and the base plate 12.

[0045] In addition, the static pressure display device 100 of the range hood also includes a connector for connecting the load-bearing component to the mounting component 20.

[0046] It is understandable that the connecting part can be a trailer part, and the load-bearing part can be a vehicle. One end of the trailer part is connected to the vehicle, and the other end is connected to the mounting part 20. When the range hood 200 is powered on and started, the air intake 210 generates suction on the adsorption chamber 11. The suction force and the vehicle's weight form an opposite force, and the vehicle can move under the suction of the range hood 200. This allows consumers to intuitively feel the air volume and air pressure of the range hood 200, thereby demonstrating the performance of the range hood 200, meeting consumers' psychological expectations, and making it easier for consumers to choose their favorite product.

[0047] The trailer hitch can be a tow rope, with one end attached to the trailer hitch 20 and the other end attached to the vehicle's trailer hook. Alternatively, one end of the tow rope can be equipped with a hook, which is attached to the trailer hitch 20.

[0048] Alternatively, the mounting component 20 is a single unit, which is located at the bottom center of the adsorption assembly 10. This ensures that the adsorption assembly 10 remains balanced when subjected to the weight of the load or the tension transmitted by the connector, and that the suction force generated by the air inlet 210 on the adsorption chamber 11 is also balanced. This reduces the force error between the mounting component 20 and the adsorption assembly 10, and makes it easier to demonstrate the suction power of the range hood 200.

[0049] Alternatively, multiple mounting pieces 20 may be used, spaced apart at the bottom of the adsorption assembly 10. These mounting pieces 20 are symmetrically arranged about the central axis of the bottom of the adsorption assembly 10. This ensures that the adsorption assembly 10 remains balanced when subjected to the weight of the load or the tension transmitted by the connectors, preventing it from leaning towards any single mounting piece 20. This creates a repulsive force between the suction and the forces acting on the multiple mounting pieces 20, allowing the consumer to directly perceive the airflow and air pressure of the range hood 200. For example, four mounting pieces 20 may be used, corresponding to the four corners of the base plate 12.

[0050] The static pressure display system 1000 for a range hood according to this utility model includes: a range hood 200, a load-bearing component, and a static pressure display device 100 for the range hood in the above embodiment. The range hood 200 is provided with a suction panel 220 having a suction port 210. When the range hood 200 is running and the opening of the suction chamber 11 of the static pressure display device 100 is connected to the suction port 210, the range hood 200 forms a negative pressure in the suction chamber 11 through the suction port 210, thereby allowing the static pressure display device 100 to be adsorbed onto the suction panel 220. The load-bearing component is connected to a mounting component 20 and applies a force opposite to the suction force of the range hood 200 to the static pressure display device 100 through the mounting component 20, thereby displaying the static pressure of the range hood 200 during operation while resisting the suction force of the range hood 200. By connecting the opening of the adsorption chamber 11 of the static pressure display device 100 to the air inlet 210 of the air intake panel 220 on the range hood 200, when the range hood 200 is running, the air intake 210 generates suction on the adsorption chamber 11, and a negative pressure is formed between the air intake panel 220 and the adsorption chamber 11. The gravity on the mounting component 20 and the suction generated by the range hood 200 form a repulsive force. The process of gravity and suction opposing each other allows consumers to intuitively feel the air volume and air pressure of the range hood 200, thereby fully demonstrating the performance of the range hood 200, meeting consumers' psychological expectations, and making it easier for consumers to choose their favorite products.

[0051] Optionally, such as Figure 7As shown, the width of the air intake 210 is L1 and the length is L2; ​​the width of the opening of the adsorption chamber 11 is L3 and the length is L4; the adsorption assembly 10 includes a sealing member 18, which is sealed to the air intake panel 220. The inner periphery of the sealing member 18 defines the opening, and the width of the outer periphery of the sealing member 18 is L5 and the length is L6; the width of the air intake panel 220 is L7 and the length is L8; wherein, L1, L2, L3, L4, L5, L6, L7 and L8 satisfy the following relationship: L1≤L3<L5≤L7; L2≤L4<L6≤L8.

[0052] It is understandable that the widths of the air intake 210, the opening width of the adsorption chamber 11, the outer periphery width of the seal 18, and the width of the air intake panel 220 should be within a reasonable range. If the widths of the air intake 210, the opening width of the adsorption chamber 11, the outer periphery width of the seal 18, and the air intake panel 220 decrease sequentially, it will lead to a waste of material in the adsorption component 10 and will not be able to guarantee the seal between the air intake 210 and the adsorption chamber 11. Gravity and suction will not be able to effectively counteract each other. If the widths of the air intake 210, the opening width of the adsorption chamber 11, the outer periphery width of the seal 18, and the air intake panel 220 increase sequentially, the seal between the air intake 210 and the adsorption chamber 11 can be guaranteed, gravity and suction can be effectively counteracted, and consumers can intuitively feel the air volume and air pressure of the range hood 200.

[0053] The lengths of the air intake 210, the opening length of the adsorption chamber 11, the outer periphery length of the seal 18, and the length of the air intake panel 220 must be within a reasonable range. If the lengths of the air intake 210, the opening length of the adsorption chamber 11, the outer periphery length of the seal 18, and the length of the air intake panel 220 decrease sequentially, it will lead to a waste of material in the adsorption assembly 10 and will not guarantee the seal between the air intake 210 and the adsorption chamber 11. Gravity and suction will not be effectively counteracted. If the lengths of the air intake 210, the opening length of the adsorption chamber 11, the outer periphery length of the seal 18, and the length of the air intake panel 220 increase sequentially, the seal between the air intake 210 and the adsorption chamber 11 can be guaranteed, gravity and suction can be effectively counteracted, and consumers can intuitively feel the air volume and air pressure of the range hood 200.
